WATCH: Cameron Diaz Tells Oprah She Is Vehemently Against The Term ‘Anti-Aging’

As if overnight, turning 40 has suddenly become the most alluring milestone in the world. Bronzed, taut and glowing actresses like Gwyneth Paltrow, Julia Roberts and Cameron Diaz are marching into their 40s with an almost revolutionary wisdom—while becoming trusted lifestyle gurus along the way.

Cameron Diaz, author of The New York Times bestseller The Body Book, most recently told Oprah during an interview for Oprah Prime that there’s no such thing as "anti-aging," and Oprah passionately agreed. As the 41-year-old actress argued, aging is both natural and unavoidable, and women should embrace time’s process.

"Our culture is obsessed with not growing into who you were really to be," comments Oprah. "Like we’re supposed to now apologize for being who you are and where you are and what it took you to get here."

Cameron went on the explain, partly sarcastically: "We don’t honor the journey and who we are and how much we have to offer…It’s almost as if we have failed if we don’t remain 25 for the rest of our lives. Like, we are failures. ‘Oh, I’m sorry, I apologize. I wasn’t able to defy nature.’"
